SUBMARINE RQAT.

[ all whom "it may concern:

Be it known that I, RAYMOND DE UEVIL- LEY-MONTJUSTIN, a subject of theKing of Spain, and a resident of Kiel, in the Empire of tier-many, haveinvented certain new and U useful Improvements in Submarine Boats, 7 ofwhich the following is a specification.

The present invention relates to submarine boats with ejecting tubes fortorpedoes and 0' the main feature of the invention is that the ejectingtubes are completely inclosed in a housing arranged exterior to the hullproper ofthe boat.

The accompanying drawings show one embodimentlofthe invention by way ofexample.

Figure l is a top view, partly in section, of a submarine boat; Fig. 2is a section on line 22, Fig. 1, looking from the left, and

Fig. 3 is a longitudinal section through one of the torpedo tubes, on anenlarged scale.

The outer wall A of the hull proper is surrounded by a second wall Onthe top of the wall B is arranged a superstructure C which extendsthroughout the entire length of the boat and which is filled withsea-water during the travel below the surface. The superstructure C hasan outer shape which guarantees stability of the craft and oiferstheleast possible resistance to the travel of the boat.

\Vithin the superstructure C a plurality of ejecting tubes D arearranged in such a manner that torpedoes can be ejected in any directionwithout necessitating any great turning of the boat. The ejecting tubesare completely inclosed in the housingC. The number of ejecting tubes isequal to the number of torpedoes to be carried along. 40 The ejectingtubes are prr vided with hinged flaps cl which permit theintroduction-of the torpedoes into the ejecting tubes and thesuperstructure is provided with hinged flaps c which permit the ejectionof the torpedoes. The free space of the ejecting tube loaded with atorpedo is constantly filled with a liquid, such as heavy oil, whichdoes not attack the-wall of the torpedo and is of a density which is asnearly as possible equal to that of the sea-water. As furthermore theweight of the torpedo is also approximately equal to the weight of thesea-water, the seawater which enters the ejecting tube after theejection of a torpedo will have a weight which is approximately equal tothe weight Specification of Letters yatent.

passes out with the torpedo. It is, therefore, unnecessary to providespecial devices for compensating Ior the weight of an ejected torpedo.The invention furthermore pretion and that special compartments in theare done away with. As compared with the known submarine boats in whichthe hull proper the arrangement of the ejecting tubes in asuperstructure presents the advantage of less resistance to the travelof the boat and makes it possible toeject the tor pedoesalso duringsurface-travel. Furthermore, the herein-described arrangement of theejecting tubes makes it possible to more heavily arm a submarine boat ofa given tonnage. Finally, the ejecting tubes may,

in such a manner that it is possible to eject the torpedoes toward thesides of the boat.

Having thus described the invention, what is claimed and desired to besecured by Letters Patent is l. A submarineboat having an inner hull, anouter hull inclosing said inner hull and spaced therefrom, a housingarranged above and exterior to said outer hull, and torpedo tubesarranged within and inclosed by said housing.
